This invention relates to dispensing apvtion there 1s shown a can of vconventional paratus and has special reference to a dispensing can for the dispensing of volatile and inammable liquids.

One important object of the invention is to provide an improved' can of this character wherein the contents will be normally sealed from evaporation..

A second important object of the invention is to provide an improved can of this character wherein provision is made for releasing vapor pressure generated when the can becomes overheated and that without result of the contents of the can exploding.

A third important object of the invention is to provide an improved dispensing can so arranged that normally no air can reach the gas or liquid confined therein. A

A fourth important object of the invention is to provide an improved can of this character having novel means for readily refilling and emptying the can of its contents.

A fifth important object ofthe invention is to provide a can of this character 'with i' means to prevent the contents from being carelessly or accidentally spilled when thereceptacle is overturned or is by inadvertence left lying on its side or in an inverted position.' I

With the above and other objects in view as will be hereinafter apparent, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings and specifically claimed.

. In the accompanying drawings like characters of reference indicate like parts in the several views, and:

Figurevl is a vertical transverse section through the can with certain of the parts shown in elevation.

Figure 2 is a plan view of the -improved can.

Figure 3 is a section on the line 3--3 of .Fi re 1. igure 4 is an enlarged detail section through the delivery spout. V

j Figure 5 is a section on the line 5-5 of Figure 4.

In the present embodiment of the invenoblong form having a side wall 10, bottom 11 and top 12. The parts are all secured hermetically together'by seaming and beading as indicated at 13. In vthe top 12 adjacent one side of the can isa suitable opening wherethrough extends the 4lower neck or stem 14 of a filling spout 15 which has a flange 16 circumferentially surrounding the upper part at the bottom thereof'and resting on the top 12. This fiange is secured to the top by any desired hermetic means as by brazin or the like and-is additionally secured by rivets 17 which pass through the flange, the top 1.2 and through a reinforcing ring 18 resting against the underside of the top 12 beneath the flange 16. Thus this spout .is fixed firmly in position. Projecting toward the center of the can from the spout is a pair of ears 19 through vwhich passes a headed pin 20. This pin likewise passes through downwardly projecting lugs or ears 2 1 formed on the closure cap 22,. This closure cap has a downwardly extending vertical flange 23 connecting the lugs or ears 21 A vand surrounding the pin 20 is a spring 24,

one end 25` of which bears beneath the fiange 23 while the other end 26 engages beneath l one of the lugs 19 'so that the cap 22 is always urged to closed position.' The upper end of the spout is provided with a lip 27 which engages against a suitable packing washer 28 held in a groove on the underside of the cap 22. This cap 22 has an opening 29 therethrough and about midway the height of this opening is an inwardly projecting flange '30 against the underside of which is fixed a foraminous disk 31. The upper end of the opening 29 is also shouldered and on this shouldered portion rests an imperforate disk y 32 which is secured in position by a fusible brazing alloy or may even itself be made of fusible metal. At the front side of the cap 22 there is provided a lug 33 in which is pivoted a latching loop 34 which, when the cap is closed, swings downwardly as shown in Figure 1 to engage a latching lug 35 secured to the spout by a suitable fuslble braging 1m alloy.

Riveted or otherwise secured to the neck 14 is a foraminous strainer tube 36, the side walls of which are pressed together at the bottom and in which the bottom opening is closed by' a suitable closure 37. This tube has its lower end extending through an opening formed in a baflle plate 38 which divides or the like. Naturally, there will be above the liquid itself a volume of vapor which will commonly consist of air mixed with vapor-ized volatile liquid and is thus consequently of a m'ore Vor less explosive' nature. Obviously, if it is desired to pour from the can the latching loop 34 is swung clear of the lug 35 and is used for a finger loop to raise the cap 22 against the action of the spring 24 whereupon the can may be poured from. Similarly, in filling the cap isthus raised. N ow, if in the process of filling or emptying any of the liquid flowing out or the exterior vapor becomes ignited the can will not explode because of the fact that no llame can reach any portioii of the interior of the can except that within the minutely foraminous tube 36. Moreover, should the can at any time be exposed to abnorm'al heat conditions so that the pressure within the can becomes excessive or the heat surrounding the can becomes excessive then the closure 32 will be released andl the volatile liquid will escape through the minute openings in the foraminous plate 3l and in this manner flame will be prevented from reaching the interior of the can so' that there can be no explosion of the can itself since to make such an explosion flame must reach the interior. This provides a can which is perfectly safe from accidental explosions. For instance, it would be possible to place a can of this construction in the middle of a fire and the only result would be that the escaping vapor would burn on top of the foraminous disk or closure 3l and this would continue until all of the contents of the can had evaporated without'the can itself exploding.

nThere has thus been provided a simple and efficient device of the kind described and for the purpose specified.

It is obvious that minor changes may be made in the form and construction of the invention without departing from the m'aterialspirit thereof. It is not, therefore, desired to confine the invention Ato the exact form herein shown and described, but it is desired to include all such as properly come within the scope claimed.

lHaving thus described the is claimed as new, is:

invention, what fop.

ceptacle at one side of the delivery. opening,

a fusiblemember cooperating with the clo-- sure to h old the latter closediover the opening, a disk normally closingthe closure opening and adapted automatically to free the closure opening under abnormal .heat conditions, and a -foraminous tube extending downwardly from around said delivery opening and having a closed bottom, the sum of the cross sectional areas of the foramina in the tubebeing greater than the cross sectional area of the delivery opening.

2. In a volatile liquid container, a receptacle having a delivery opening, a closure for said opening having an opening communicating with the delivery opening, said closure having hinge connection with the receptacle at one side of the 4deliveryv opening,

a fusible member cooperating with the 'closure to hold the latter closed over the opening, a disk normally closing the closure opening andA adapted automatically' to free the closure opening under abnormal heat conditions, a rforaminous diaphragm inthe closure opening between said disk and the delivery opening, and a foraminous tube extending downwardly from around said delivery opening and having a closed bottom, the sum of the cross sectional areas of the foramina in the tube being greater than the cross sectional area of the delivery opening.

3. In a volatile liquid container, a receptacle having a delivery opening, a closure for said opening having an opening communicating with the delivery opening,l a disk normally closing the closure opening and adapted automatically to free the closure opening under abnormal 1. heat conditions, a foraminous diaphragm in -the closure opening .between said. disk and the delivery opening, a foraminous tube extending downwardly fromAl around said delivery opening and having a closed bottom, the sum of the cross l sectional areas yof the fo'ramina in the tube being greater than .the cross sectional area of the delivery opening, and spring means between the'first mentioned closure and the receptacle normally tending to retain the former in closed position; y c In testimony whereof I aflix my signature'.
